A series of self-immolative linkers containing a thiol-reactive group at one end and a hydroxyl- or amine-reactive group at the other were prepared. The utility of these reagents for preparations of bioconjugates was explored by reacting the linkers with appropriately functionalized model drugs and peptides. Degradation studies of a series of conjugates with different linkers reveal that the structure
制备了一系列在一端含有
硫醇反应性基团而在另一端含有羟基或胺反应性基团的自消灭性连接基。通过使接头与适当官能化的模型药物和肽反应,探索了这些试剂在制备
生物缀合物中的效用。一系列具有不同接头的缀合物的降解研究表明,接头的结构对其稳定性具有重大影响。
